The correct answer to the question is option 'A': the bulb glows momentarily.
Explanation:
When a circuit is broken suddenly, there is a brief moment where the current is disrupted. In this scenario, the circuit consists of a series connection of coil C1 and a very small diwali bulb, and another coil C2 connected to a battery.
When the connection is snapped, the circuit is suddenly broken, causing a change in the current flow. This change in current induces a temporary voltage in the circuit due to the self-induction effect of coil C1.
The self-induction effect occurs when the magnetic field produced by the current flowing through a coil changes, causing a change in the magnetic flux through the coil. This change in flux induces a voltage in the coil, which opposes the change in current.
In this case, when the circuit is broken, the current through coil C1 decreases suddenly. This change in current induces a temporary voltage in the coil, which results in a momentary glow of the bulb.
However, it is important to note that this momentary glow is very brief, as the self-induction effect quickly dissipates the energy stored in the coil.
It is also worth mentioning that coil C2, connected to the battery, is not affected by the sudden breaking of the circuit. The current through coil C2 continues to flow without any interruption.
To summarize, when the connection is snapped:
- The sudden change in current through coil C1 induces a temporary voltage in the circuit.
- This induced voltage causes a momentary glow in the bulb connected in series with C1.
- The glow is brief and quickly dissipates as the self-induction effect dissipates the energy stored in coil C1.
- Coil C2, connected to the battery, is not affected by the sudden breaking of the circuit.
